Resistance tests of a series of planing hull forms with 25 degrees deadrise angle1

Abstract

In 1963 E.P. Clement and D.L. Blount published the results of resistance tests of a systematic series of planing hull forms generally known as the TMB Series 62 or the Clement Series . In order to update this work a systematic model experiment has been carried out with identical models to those used in the Clement and Blount series but with a deadrise angle of 25 degrees. These models have been tested with the same variation in design variables as in the original tests, the influence of the length-beam ratio, the weight of the vessel and the longitudinal position of the centre of gravity has been examined, but the speed range has been reduced from 0.5 < Fn < 6.0 in the Clement tests to 0.75 < Fn < 3.0 in the present tests. The results are presented in graphical and tabular form.
